ENGINE OIL

Use a clean, high quality detergent oil. Be sure original container is marked: A.P.I. service SF thru SJ. The use of
multigrade oil may increase oil consumption under high temperature, high load applications.
NOTE: DO NOT USE SAE10W40 OIL.
For summer (above 32°F, 0
load applications.
S.A.E.10W30 is an acceptable substitute.
For winter (below 32°F, 0
S.A.E.10W is an acceptable substitute.
S.A.E. 0W30 should only be used when ambient temperature is below 0

Oil Change Intervals. Change the oil after the first two (2) hours of operation and every 25 hours thereafter, or more
often if operated under dusty or dirty conditions, extreme temperature, or high load conditions.
Oil Check. Check the oil each time the equipment is used or every 5 hours. Position the equipment so the engine is
level when checking the oil.
CAUTION: REMOVE THE SPARK PLUG WIRE BEFORE DOING ANY SERVICE WORK ON THE ENGINE.
Oil Change Procedure: Locate the oil drain plug. On some units this plug is located below the deck through the
bottom of the mounting flange. Other units drain at the base of the engine above the deck or frame. If access to the
drain plug is restricted by the equipment it may be necessary to drain the oil by tipping the mower in a position that
would allow the oil to drain out of the fill tube.
On units that the drain plug is accessible, remove the plug and allow the oil to drain into a proper receptacle. Always
make sure that drain oil is disposed of properly.
Once the oil is drained, reinstall the plug and fill the engine with new oil to the proper capacity.

TUNE-UP PROCEDURE.

The following is a minor tune-up procedure. When this procedure is completed, the engine should operate properly.
Further repairs may be necessary if the engine's performance remains poor.
CAUTION: REMOVE THE SPARK PLUG WIRE BEFORE DOING ANY SERVICE WORK ON THE ENGINE.
1. Service or replace the air cleaner as needed.
2. Inspect the level and condition of the oil and change or add oil as required.
3. Remove the blower housing and clean all dirt, grass or debris from the intake screen, cylinder head, cylinder
cooling fins, carburetor, governor levers and linkage.
4. Make sure the fuel tank, fuel filter and fuel line are clean. Replace any worn or damaged governor springs or
linkage. Make the proper governor adjustments and carburetor presets where required.
